Why are you removing it without testing it? It's rare for them to go bad. The temperature switch wiring circuit is independent of the A/C compressor circuit. They use the same relay but the grounding legs are activated separately.

Test the switch by running the car until the temperature gauge reads apx. 105C (220F). If the fan doesn't come on, THEN replace the switch/sensor.

The temperature sensor plays no part in the fan operating when the A/C is engaged. That is controlled by the A/C circuit.
